ELECTRIC CUTTER FOR PAPER-TUBE MACHINES.

Specification of Letters Iatcnt. Patented N 23 192 Application filed February 20, 1918. Serial No. 218,292.

To all whom it may concern:

Be it known that I, Q'r'ro H. Ronssnmc, a subject of the King of Belgium, (having declared my intention of becoming a citizen of the United States,) and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Electric Cutters for Paper-Tube Machines, of which the following is a specification.

My invention relates to certain improvements in machines for automatically cutting paper tubes into lengths andiis designed to be attached to, or to form a con tinuation of, a tube forming machine, such as set forth in the patent granted to me on the second day'of July, 1918, No. 1,271,370.

One object of the invention is to design a machine which will cut off tubes, all of a given length by electrically operated mechanism.

A further object of the invention is to provide automatic means for controlling the tube itself.

The invention also relates to imrovements in details, which will be ful y described hereinafter, reference being had to the accompanying drawings, in which:

Fig. 20 is a detached perspective view of the trip lever of the releasing mechanism.

Referring to the drawings, 1 is the frame of a tube forming machine, such as that illustrated in the above mentioned patent. 2 is the frame of the cutting off mechanism to which my invention relates. 3, 3 are the final rolls of the tube forming machine. 4 is a guide through which the finished tube is tied, and this guide is reduced at 5 to abo'gt the diameter of the tubeso that the tube will be held in the proper position to be cut by the rotating blade 6, which will be described hereinafter. 7 is a trough into which the tube is fed from the tube forming machine, and at the end of this machine is trip mechanism. 8 having a plate 9 'located in the path of the tube so that when the tube at strikes this plate, as in Fig. "2, it actuates-the electric mechanism which-controls the cutting 'oif mechanism and which opens the trough and allows the tube to be discharged at one side of the machine.

The mechanism above set forth is intended to cut tubes of a given length and while it can be adjusted, the adjustment is limited and-if tubes of other lengths are desired a separate machine is used in which the displate is greater or less. according to the length desired for the finished tube.

The machine of the above entitled patent makes what is known as a continuous tube. 71. e., a tube of considerable length from strips of paper assembled in tubular form and pressed into shape. This continuous tube must be cut into given lengths, the length depending entirely upon the use for which the tube is intended. The tube. after passing between the rolls, Fig. 3. as before remarked, passes through the die 4 and out through said die onto the trough 7.

The cutter illustrated in Figs. 3. 10, 11, 13 and 14, is circular in form and has a sharp edge and is mounted on an arm 10 of a lever 11 pivoted on' a shaft 12 adapted to bearings in the frame of the machine. The end 13 of the lever 11 is adapted to ride upon a cam 14 pivoted at 15 to the arm 16. Fig. 4, and return under the cam so that when the lever carrying the cutter is moved away from the die 4, the arm 13 rides upon he cam 14. forcing the cutter toward the projecting tube and moves in front of the die, cutting the tube ofi at the proper point. The movement of the tube is substantially continuous and the short longitudinal movement of the cutter lever allows the cutter to act and to cut the tube at right angles to its length, thus insuring a clean cut of the tube.

On one end of the cutter shaft 17 is a pinion 18 which meshes with a gear wheel 19, loose on the shaft 12, and on the hub of this gear wheel 19 is a grooved pulley'20. over which passes a belt 21 from a grooved pulley 22 on a jack shaft 23 mounted in the lower portion of the frame. This shaft is driven from the main shaft 24 by a belt 25. The main shaft 24 is mounted in bearings on the frame 2 and on this shaft is a gear wheel 26 which meshes with a pinion 21 on the shaft of a motor 28, the motor in the present instance being an electric motor. The shaft 20 also drives the shaft 29 of the tube forming machine, in the present instance.

he driving shaft 29 in turn drives the lower roll of the pair of rolls 3, which are the final rolls of the tube forming machine.

These rolls feed the tube toward the cutting mechanism. This construction is fully described in the patent hereinbefore mentioned.

The trough 7 is made in two parts. as clearly shown in Fig. 9. One part 30 is fixed and is-secured to a bracket 31 secured to the frame 2 and has a series of guide rods 32 spaced a given distance apart and inclined. as clearly shown in Fig. 9, so as to carry the discharged tube to one end of the machine. The other half 33 of the trough is carried by arms 34, 34 pivoted at 35 to the brackets 31. The arm 34 has an extension 36 to which is adapted a cord 37. which passes around a pulley 38 and is connected to a rod 39, which extends through a bearing 40, and

this bearing has a head 41. On the rod is a oiled spring 42. This spring is inactive and merely acts as a buffer when the rod 43 carrying the bearing 40 is moved longitudinallv in the direction of the-arrow, Fig. 5 so that when the parts are in the position illustrated in said figure the trough is closed, retaining the tube until it is cut off. when the mechanism will be operated which will cause the trough to open and to discharge the cut off tube.

The shaft 12 is secured at one end to a side head 60 and projecting from this slide head at the opposite end is a rod 43.

On the driving shaft 24 is a worm 44-. which meshes with a worm wheel 45 on a shaft 46 and on this shaft is a sprocket wheel 47 around which passes a chain 48 to a sprocket wheel 49 on a shaft 50. On this shaft 50 is a sprocket wheel 51 around which passes a chain 52 which also passes around a sprocket wheel the shaft of which is mounted in a fixed hearing The shaft 49 is mounted in an adjustable bearing which can be adjusted by a screw 56 in the ordinary manner so as to take up the slack due to the wear of the chains. On the chain 52 are one or more lugs 57. which come in contact with a forked trip lever 58 which straddles the block 61 pivoted at 62 to the slide head 60. On this clock 61 is mounted a solenoid magnet 63, the armature 64 of which is connected by a pin (35 to the lever 58, the pin passing through a slot in said lever. The pivot pin 59 on ,which the trip lever 58 is mounted on the block 61 extends at each side and is adapted to hotches in the slide head so as to limit the downward movement of the block 61 and the trip lever.

When the traveling lug 57, which moves in the direction of the arrow, Fig. 10, comes in contact with the trip lever 58. i't-moves the. block 61 at the same speed as the tube, as indicated in Fig. 11. and when the horn (36 on the block comes in contact with the fixed roller 67 secured to a bracket 68 on the frame of the machine it is forced up by the roller. Fig. 11. and the trip lever is gradually released from the lug 57, as illustrated in Fig. 11. and a spring 69. which is located between the hub 20 and a bearing 54 forming a continuation of the bearing 54, retracts the rod 12 to which the slide head 60 is attached. and moves it quickly in the direction of the arrow. Fig. 12. The return movement causes the trip lever to turn on its )ivot, moving the armature 64 of the magnet 63 to its outer position and the end of the trip liver will be clear of the lug 57 so that it will pass the releasing mechanism without action until the magnet is energized by the paper tube coming in contact with the plate 9 of the tripping mechanism. which makes the contact. energizes the magnet, causing the magnet-to draw in the armature and to turn the trip lever 58 on its pivot, when it will assume the position illustrated in Fig. 10 with its end in the path of the lug 57.

On the upper end of the trip lever is a bent arm having a counter weight 71, which will properly balance the lever. On one end of the slide head are contacts 72 and 7 3, which come in contact with terminals 74 and 75 respectively mounted on'the hearing 54 when the slide head is returned to its normal position, as illustrated in Fig. 3*, so that when the tube'strikes the plate 9and causes it to make contact the magnet is energized and the trip lever is moved from the position shown in Fig. 12 to the position shown in Fig. 3*, so that it will be in the path of a lug 57 on the chain 52, allowing it to be tripped so as to actuate the cut off tool and discharge the section of the tube.

The tripping mechanism is mounted on a bracket 75, projecting at the end of the ma chine, as clearly shown in Figs. 1 and 7. On this bracket is an undercut slideWa-y 76 in which is mounted the base 77 of a slide head 78. Located between the two bearings 79 and 7 9 on this head is the trip plate 9, in the present instance having a projection 9. On a bracket 89 are two terminals 81 and 81" connected to the terminals 74 and 75 respectively. The projection 9 'isforced between these two contacts 81 and 81 when the trip plate 9 falls by the end of the tube strik ing it.

It will be noticed that the trip plate, 9. when raised, is; beyond the line 3 Fig. 7, and the tube, when it strikes it, pushes it past the center and it falls by its own weight. connecting the contacts and closing theelectric circuit, which energizes the magnet (53 so that it will shift the trip lever 58 to the position illustrated in dotted lines Fig. 3. At one side of the plate 9 is a projection 9 which is arranged to come in contact with an adjustable stop 82 in the form of a screw, which is mounted in a bracket 7 8, projecting from the slide head, and which regulates the position of the plate. On the rod 43, Fig. 5,'is a collar 83 in which is a post 84 and attached to this post is a tension spring 85 which is secured to a cord 86, extending to the trip mechanism and is attached to a pin 87 on the grooved wheel 88, which is mounted on the slide head 78. This wheel is mounted on the same pivot as the plate 9, in the present instance, and has an arm 89 provided with a weight 90. On the disk oil the grooved wheel 88 is a pivoted pawl 91, which is arranged to engage the teeth of a'ratchet wheel 92 located on the same spindle as the wheel 88. 93 is a spring which tends to yieldingly force the pawl into engagement with the teeth and 94 is a stop and release,

which engages the pawl when it is returned.

to the position illustrated in Fig. 7 so as to force it out of engagement with the wheel position, as illustrated in Fig. 7, and on this wheel is a pin 97, which is in the path of the projection 9", so that when the wheel 92 is turned in the direction of its arrow 1 it will lift the plate, returning it to its normal position, as illustrated in Fig. 7.

The operation of the machine is as :tollows:

The formed tube is projected through the die 4 and onto the trough 7 and as it is fed forward it comes in contact with the plate 9, the parts being set as illustrated in Fig. 1. The moment the end of the tube strikes the plate 9 of the trip mechanism it pushes the plate over the center g and the plate falls to the position shown in dotted lines, Fig. 7, connecting the terminals 81 and 81, and as these terminals are wired to the terminals 74 and 75, and as the spring contacts 72 and 73 of the magnet 63 are in contact with these terminals, the magnet, will be energized and will retract the armature, shiftng the trip lever 58 to a position in the .ath of the lug 57 on the chain 52 and as the chain is moving slightly in the direction of its arrow, the lug 57 will strike the trip lever 58 and will move the slide head and rod 12, including the blade 6 and its driving mechanism in the direction of the arrow, Fig. 1, compressing the spring 69 and releasing the grooved wheel 88, which is weighted so as to allow it to turn on its pivot-1' ,This movement releases the pawl 91 from the stop 94 so that it will engage the teeth of. the ratchet wheel 92. The movement of the slide head is continued until the horn, or projection 66 comes in contact with the fixed roller 67, as shown in 'Fig. 11. which will tilt the block and withdraw the trip lever from engagement with the lug 57 on the chain. The moment this trip lever is released the spring 69, which has been compressed, returns the slide head carrying the block, trip lever, and the magnet, to their normal positions. This movement causes the wheel 88 to be returned to its normal position, as the wheel is connected to the post which is, in turn, con-' nected to the slide head and as it is returned it will also turn the ratchet wheel 92 in the 'direction of the arrow 1, due' to the fact that which tends to hold the wheel in its normal from .the ratchet teeth by the stop 94, and the weight 96 of the ratchet wheel 92 will return the ratchet wheel to its normal position, as, illustrated in Fig. '7. This action causes the movement of the bearin 40, which is connected to the side 33 o the trough, which is opened to allow the cut tube section to roll over the guides to one side of the machine. The trough is then closed and the above operation is repeated every time the tube is projected against the plate 9.

It will be seen by the above operation that this electric cut ofi. and discharge mechanism is entirely automatic and is actuated by the tube.
